What are the principles of label design? 4 visual impact techniques to boost sales by 30%
💡 💡 At a Glance
Core Principles and Practical Techniques of Label Design — From Information Hierarchy to Materials and Processes.
Last week, a snack-industry client asked me: "Our new label has been on for 3 months, and sales haven't gone up. Is there a problem with the design?"
I said: "Let me first look at your shelf competitors."
He sent 5 photos. I saw it at a glance — his label's main visual element accounts for only 18%, while the industry average is 35%.
He said, "No wonder."
I said, "Label design isn't just about looking good — it's about the visual impact that gets noticed by consumers in 0.3 seconds on the shelf." This article won't cover aesthetics; it will cover 4 real, data-backed visual techniques.
4 Visual Tricks to Boost Sales by 30%
I'm not the one saying it — it's label lab data from FMCG giants like LeShi, P&G, and Coca-Cola. Each trick is backed by eye-tracking and shelf comparison experiments.
Trick 1: Increase Main Subject Coverage from 18% to 35%
Data: Main image on label area from 18% → 35%, shelf scan rate +50% (P&G experiment).
Principle: Consumers scan shelves in 0.3 seconds; the larger the main image, the more easily it is noticed — this is the hard rule of human eye sensitivity to "large color blocks."
Implementation:
- Main image occupies 30-40% of the label
- Simple background (solid color or subtle texture)
- Do not place more than 3 elements on the label
Case: LeShi potato chips' 2019 label redesign expanded the main image from 18% to 38%, sales rose 30%.
Trick 2: 3-Level Text Hierarchy (Title / Selling Point / Description)
Data: After adjusting to a 3-level text hierarchy, the skip rate dropped from 40% to 15% (Coca-Cola experiment).
3-Level Hierarchy Standard:
| Level | Font Size | Color | Function |
|---|---|---|---|
| Main Title | 14-18pt | Primary color + bold | 0.3-sec attention grab |
| Selling Point | 9-12pt | Contrast color | 1-sec retention |
| Description | 6-8pt | Gray / white | 3-sec persuasion |
Principle: Consumers' scanning path is F-shaped (confirmed by eye-tracking) — main title at the top-left → selling point in the middle → description at the bottom. Design the text hierarchy following the F-path and the skip rate drops 50%.
Trick 3: Color Psychology (Industry Color + Psychological Color)
Industry colors (consumers' subconscious associations):
- Red / Yellow: Appetite, warmth → food, beverages
- Green: Eco-friendly, healthy → organic food, health supplements
- Blue: Technology, trust → electronics, pharmaceuticals
- Black / White / Gold: Premium, luxurious → cosmetics, luxury goods
- Red / Yellow / Blue: Lively, playful → children's products
Psychological colors (trigger emotions):
- Warm colors (red, orange, yellow): Accelerate decision-making (suited to rational purchase scenarios)
- Cool colors (blue, green, purple): Extend decision-making (suited to experience-based consumption)
- High-brightness colors: Youthful, energetic
- Low-brightness colors: Mature, steady
Implementation: Use industry colors for the primary color (maintain brand tone), psychological colors for secondary colors (trigger emotions), contrast ratio ≥ 30% (ensure readability).
Trick 4: Avoid Same-Shelf Competitor Colors
Principle: When users scan the shelf, same-color blocks are skipped as a whole — this is the "visual chunking effect."
Cases:
- A certain cola placed next to red-can Coke — users scan and treat the entire red block as the "cola zone," unaware there are other brands.
- A certain mineral water placed next to blue Nongfu Spring — same as above.
Implementation:
- Check the colors of 5-10 competitors on the same shelf
- Avoid competitors' colors for your primary color
- Use contrast or complementary colors to "stand out"
Real Data Comparison of 4 Techniques
| Technique | Before Adjustment | After Adjustment | Data Change |

| Main Image Proportion | 18% | 35% | Scan Rate +50% |
| Text Hierarchy | 2 Levels | 3 Levels | Skip Rate -62% |
| Color | Following Competitors | Contrasting Color | Brand Recognition +40% |
| Shelf Color | Same Color | Different Color | Pick-Up Rate +25% |

FAQ
What are the core principles of label design?
4 core principles: (1) Main visual contrast — the hero image occupies 30-40% of the label, with a clean background; (2) Reading order — the 3-second rule, following the sequence of headline, selling points, and brand; (3) Color psychology — green for eco-friendly / red for appetite / blue for technology; (4) Information hierarchy — 3 levels (headline 14pt, selling points 9pt, description 6pt). Violating any of these will get your product buried on the shelf.
Can label design boost sales?
Yes. 3 experimental data points: (1) For the same product, sales increased by 30% after a label redesign (Lay's chips case study); (2) Expanding the hero image by 20% boosted shelf scanning rate by 50% (P&G experiment); (3) Adjusting text hierarchy reduced skip rate from 40% to 15% (Coca-Cola experiment). Visual impact is the most cost-effective way to drive sales at the shelf.
What are the considerations for label design color matching?
3 dimensions: (1) Industry colors — food often uses red, yellow, and green (appetite appeal), cosmetics use black, white, and gold (premium feel), children's products use red, yellow, and blue (vibrant energy); (2) Contrast — the brightness difference between the primary and secondary colors should be ≥ 30%; (3) Competing products on the same shelf — avoid using the same colors as similar products (consumers tend to skip same-color blocks during scanning). The specific palette is recommended to be 4-5 main and accent color combinations, with no more than 7 colors.
Is the 3-second rule for label design real?
It is real. The average shelf scanning speed in supermarkets is 0.3 seconds per item, and 3 seconds is the upper limit for a consumer to decide whether to stop. Eye-tracking data shows: consumers scan in 0.3 seconds, make a judgment in 1 second, and decide whether to pick up the product within 3 seconds. Therefore, label design principles are: (1) within 0.3 seconds, capture attention with the hero image; (2) within 1 second, hold attention with selling points; (3) within 3 seconds, convince with the brand. These 3 levels work progressively.
Do I need to hire a designer for label design?
It depends on the scenario. (1) Mass consumer goods (food, beverages) must have a designer — the label is critical to sales; (2) Industrial products (B2B parts) can use templates + font libraries; (3) Personalized products (gift boxes, private customization) are recommended to be designed by yourself + optimized with an AI assistant. For beginners, it is recommended to find a designer with FMCG experience for the first version, at a price of 500-2000 RMB per version (excluding printing).
